Description

Pressing pump head Technical Field The utility model relates to a liquid outlet device, in particular to a pressing pump head. Background The existing pump head generally comprises a pump chamber, a pressing piece and a liquid inlet pipe, after the liquid in the bottle enters the pump chamber through the pressing piece, the liquid in the pump chamber is pressed again, the liquid in the pump chamber is discharged through the pressing piece, and a one-way valve and a piston structure are generally needed to complete the process, wherein the one-way valve is used for preventing the liquid from flowing backwards, and the piston structure is used for sealing a gap between the pump chamber and the pressing piece, so that the liquid is prevented from entering the gap, and the final liquid outlet effect is influenced. The prior pump head generally passes through one-way valve when liquid in a bottle enters a pump chamber, and passes through a second one-way valve when liquid in the pump chamber is discharged through a pressing piece, and the piston structure and the one-way valve are mutually independent in the structure, so that the structure is relatively complex. Disclosure of Invention In order to overcome the defects in the prior art, the utility model provides a pressing pump head. The technical scheme adopted for solving the technical problems is as follows: The utility model provides a press pump head, includes the lid and presses the piece, be provided with the reservoir in the lid, press a movable mounting to be in the reservoir, the center of reservoir is provided with wears to establish the passageway, press the piece to correspond wear to establish the passageway and be provided with the feed liquor pipe, the lower extreme of feed liquor pipe is provided with the ring channel, the lower extreme of ring channel is provided with the inlet, lie in on the feed liquor pipe be provided with slidable shutoff in the ring channel or reveal the piston of inlet. The pushing piece capable of sliding in the penetrating channel is integrally formed in the penetrating channel, and a liquid inlet channel is arranged in the pushing piece. The pushing piece is integrally formed with the penetrating channel through the sheet and presses the pressing piece, the pressing piece pushes the pushing piece to enable the sheet to be completely broken, and the pushing piece slides in the penetrating channel. The upper end of the pushing piece is provided with an inserting part, the lower end of the liquid inlet pipe is provided with an inserting groove corresponding to the inserting part, the pressing piece is pressed, the inserting part is inserted into the inserting groove and pushes the pushing piece to move, and when the pressing piece is loosened to reset, the pushing piece and the liquid inlet pipe synchronously move upwards. The device also comprises an elastic liquid inlet pipe, wherein the upper end of the elastic liquid inlet pipe is propped against the pushing piece, and the lower end of the elastic liquid inlet pipe is propped against the bottom of the container, so that the elastic liquid inlet pipe is always in a compressed state.
